Recalling Key Components of the Delivery Cost Model

In Sam's weekly delivery van cost model, the linear equation is given by C=0.5m+60C = 0.5m + 60, where CC is the total weekly cost in dollars and mm is the number of miles driven.

Write a short essay recalling and defining the key mathematical and business components of this model. In your response, address the following:

  1. State the numerical value of the slope and recall its real-world interpretation as a variable cost per mile.
  2. State the numerical value of the C-intercept (or write it as a coordinate point) and recall its real-world interpretation as a fixed weekly baseline cost.
  3. Identify which of these two components represents the cost of driving zero miles.
